摘要 目的 对鸡盲肠菌群的厌氧连续培养方法及培养物的生理生化的特性进行初步研究。方法用鸡盲肠内容物接种连续培养装置 ,进行厌氧连续培养 ,稀释率为 0 .0 4h- 1 ,运转 7~ 10 d后达到稳定状态。在稳定状态时 ,对培养系统中的菌群结构、p H、OD值以及挥发性脂肪酸 (VFA)进行了分析。结果 当该培养系统过到稳定状态时 ,培养物的 p H、OD值 ,以及 VFA的产量都达到了一个相对稳定的水平。结论 有机酸中的丁酸、乙酸、丙酸等维持在一个较高的水平 。 A research on continuous flow culture derived from chicken ceacal contents was conducted.This culture system reached a steady state after running of 7 10 days when dilution rate was 0.04h 1 .The results indicated that the VFA (volatile fatty acids),pH,OD 600 reached a relatively stable levle when the continuous flow culture is in the steady state.Butyrate,acetate,and propionate maintain a high level in the VFA that may be very important to the health of animals.
